Flexural Behaviour of Non-Autoclaved Pre-Stressed High-Strength Concrete Pipe Piles with Different Rubber Contents

Buildings
Non-autoclaved pre-stressed high-strength rubber-modified concrete (NA-PHRC) pipe piles were developed to address the high energy consumption and brittleness of existing pre-stressed high-strength concrete (PHC) pipe piles.

Closed‐Loop Decoding and Intervention of Pain: A Novel BMI Strategy Integrating θ‐Band Detection and Mechano‐Electro‐Biological Coupled Hydrogels

Advanced Science, EarlyView.
A closed‐loop brain–machine interface with a PFAPT hydrogel electrode identifies prefrontal θ‐band as a neuropathic pain biomarker. The hydrogel enables stable 28 d ECoG recording and delivers θ‐triggered cortical stimulation, alleviating pain and affective behaviors in rats via bidirectional regulation of inflammation and central sensitization ...
